Abstract

The utility model relates to a multifunctional combined composite vent-pipe which has the advantages of smaller weight, convenient manufacture, high intensity, good heat preservation performance, small wind resistance and convenient cleanness. A pipe wall is formed by orderly compounding a metal sheet layer (1), a heat preserving layer (2) and a fireproof and waterproof layer (3) from inside to outside, the periphery of the pipe wall is wrapped with a strengthening hoop band (5), and two ends of a pipe body are connected with flanges (4). The utility model is used as the vent-pipe and is suitable for various wind feeding places of a central air conditioner.

Description

Multifunction combined composite ventilated pipe

Technical field

The utility model relates to ventilation equipment spare, particularly a kind of combined ventilation duct.

Background technique

Comprise the various supply air systems of central air-conditioner, all ventilation duct need be arranged.Existing this ventilation duct useful metal pipe is made as galvanized iron leather hose outsourcing thermal insulation layer, and also useful inorganic material is made.Adopt the not only cost of metal tube higher, be that more it gets rusty easily, working life is shorter, and has " cold bridge " phenomenon, makes the pipe insulation decreased performance.The ventilation duct of some inorganics, resisting expansion strength is lower, and windage is big, and has " cold bridge " phenomenon equally.Also some ventilation duct comprises organic material, and the meeting that wherein has produces toxic and harmful, is difficult to compliance with environmental protection requirements, and windage and " cold bridge " problem can not finely solve.Existing besides its cleaning sterilizing of ventilation duct is difficulty.China hygiene department requires existing ventilation duct will clean once in per 3 years, reaches sterilization, sterilization requirement, then difficult this requirement of adaptation of existing ventilation duct.A kind of ventilation duct of the applicant's No. 200420089716.5 Chinese utility application can address the above problem preferably, but this ventilation duct is owing to have the dihedral reinforcer, so deadweight is relatively large, to manufacture and also owe convenient, the Economy that adds epistasis and product also remains to be improved.

Summary of the invention

The utility model will solve that ventilation duct intensity is lower, working life is short, windage is big, thermal insulation property is low and it is easy inadequately to manufacture, the not enough economic dispatch problem of product, and a kind of multifunction combined composite ventilated pipe of the present utility model is provided for this reason.This ventilation duct can solve described these problems preferably.

For addressing the above problem, the new technological scheme that adopts of this practicality is to be associated with flange at the body two ends, and its special way is at the peripheral inclusion of tube wall the reinforcement band to be arranged.

Its tube wall of the utility model can be an individual layer, also can be MULTILAYER COMPOSITE.

Tube wall is an individual layer, and it can be made by the reinforcement special cement material that layer presss from both sides glass fibre, and its resistance to high temperature is good, is fit to do various industrial gas dischargings.

Tube wall is a MULTILAYER COMPOSITE, then from inside to outside successively by metal lamella, thermal insulation layer with the fire-proof and water-proof layer is compound constitutes.The fire-proof and water-proof layer can be made by the cement material that layer presss from both sides glass fibre, and thermal insulation layer can be made by nontoxic fire-retardant organic material, and material such as the metal lamella can aluminium flake, stainless steel sheets is made.

Reinforcement band in the utility model can be made by the materials such as iron sheet of aluminium, stainless steel, surface plastic spraying, and it is good that it adds epistasis, and weight is less, and is also both economical.Strengthen the spacing of thickness, width and the band of band and decide, generally do not have particular requirement on ventilation duct caliber, length etc.

The ventilation duct of the present utility model that is used for cold, warm air-supply, tube wall are from inside to outside by described metal lamella, thermal insulation layer with the fire-proof and water-proof layer is compound constitutes.The body two ends are associated with flange, and flange combines with flange during connection, and tube wall internal layer, an interlayer and skin are all joined with layer, have eliminated " cold bridge " phenomenon effectively and have produced good energy-conserving effect.The inside and outside layer of this ventilation duct tube wall fire-resistant, flame retardant property is strong.

The utility model is because the body skin is the fire-proof and water-proof layer, and internal layer is the metal lamella, and an interlayer is a thermal insulation layer, so have good heat preservation performance, windage is little, and fire-proof and water-proof is strong, and is not perishable, the characteristics of long service life; Owing at the peripheral inclusion of tube wall the reinforcement band is arranged, so the utility model intensity height, it is little to conduct oneself with dignity again, and manufacturing process is easier, and cost is lower; The utility model also have be convenient to clean, the characteristics of sterilization.
